In a proactive security move, a technical report revealed the discovery of three security vulnerabilities in Bitcoin Core, the core and most widely used software for running Bitcoin network nodes and verifying its transactions.
The developers quickly addressed the situation by releasing urgent updates to protect the network's stability.
๐ Details of the discovered vulnerabilities
According to the technical data, the discovered vulnerabilities vary in severity and impact on operating systems:
1. Remote shutdown vulnerability (most severe): Allows attackers to completely disable Bitcoin nodes through a memory-exhaustion attack. This vulnerability specifically affects systems running Windows, macOS, and BSD, while devices running Linux are fully immune and unaffected.
2. Gradual memory exhaustion vulnerability: Slowly and progressively consumes a nodeโs memory, causing its performance to decline over time until it stops.
3. Undo data corruption vulnerability: May corrupt the blockchainโs undo data.
๐ก๏ธ How was it discovered, and what immediate action should be taken?
These vulnerabilities were detected through an automated security scan powered by AI technologies, using Project Loupe, a tool developed by Spiral.
To ensure the networkโs safety, Bitcoin Core developers released urgent security updates and urged all node operators to upgrade immediately to one of the following versions:
Bitcoin Core 32.1
Bitcoin Core 31.2
Bitcoin Core 30.4
Bitcoin Core 29.5
๐ก Are usersโ funds at risk?
No, usersโ funds and your wallet are completely safe. These vulnerabilities are related only to โnode availabilityโ and the ability of nodes to stay connected to the network; they do not allow attackers to hack the protocol or steal cryptocurrency.
๐ด Notice to Node Operators: Update your software immediately to one of the secure versions listed above to ensure your connection to the Bitcoin network remains stable.
